Techniques for providing channel quality feedback for enhanced reliability in wireless communications

An apparatus for wireless communication, comprising:

• a transceiver;
• a memory configured to store instructions;
• and
• one or more processors communicatively coupled with the memory and the transceiver, wherein the one or more processors are configured to execute the instructions to cause the apparatus to:
• receive, from a user equipment (UE), feedback for a transmission to the UE on a downlink channel;
• generate, based on the feedback, a retransmission of the transmission to the UE using a transmission parameter that is based on at least one of a channel state information (C SI) report indicated in the feedback that corresponds to multiple sub-bands of the transmission to the UE, characteristics of uplink signaling from the UE, or a history of CSI reports from the UE;
• and
• transmit, to the UE, the retransmission based on the transmission parameter.

A method for wireless communications at a user equipment (UE), comprising:

• monitoring downlink resources for a transmission received on a downlink channel;
• generating a channel state information (CSI) report based on the transmission received on the downlink channel, wherein the CSI report indicates CSI for each of multiple sub-bands of the downlink resources;
• and
• transmitting a hybrid automatic repeat request (HARQ) acknowledgement or negative acknowledgement (ACK/NACK) feedback associated with the transmission received on the downlink channel along with the CSI report to a base station.

A method for wireless communications at a base station, comprising:

• receiving, from a user equipment (UE), feedback for a transmission to the UE on a downlink channel;
• generating, based on the feedback, a retransmission of the transmission to the UE using a transmission parameter that is based on at least one of a channel state information (CSI) report indicated in the feedback that corresponds to multiple sub-bands of the transmission to the UE, characteristics of uplink signaling from the UE, or a history of CSI reports from the UE;
• and
• transmitting, to the UE, the retransmission based on the transmission parameter.
